DTC P0097:00 [MZ-CD 1.6]
id0102g8146400
DTC P0097:00 |
Boost air temperature sensor circuit low input |
---|---|
DETECTION CONDITION
|
• The PCM monitors the boost air temperature sensor. If the input voltage is less than 0.048 V for 2 s, the PCM determines that there is an boost air temperature sensor circuit has malfunction.
|
POSSIBLE CAUSE
|
• Boost air temperature sensor connector or terminal malfunction
• Short to ground in the wiring harness between boost air temperature sensor terminal D and PCM terminal 214
• Boost air temperature sensor malfunction
• PCM connector or terminal malfunction
• PCM malfunction

Diagnostic procedure
STEP |
INSPECTION |
ACTION |
|
---|---|---|---|
1
|
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has the FREEZE FRAME DATA been recorded?
|
Yes
|
Go to the next step.
|
No
|
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
|
||
2
|
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Verify related service repair information availability.
• Is any related repair information available?
|
Yes
|
Perform repair or diagnosis according to the available repair information.
• If the vehicle is not repaired, go to the next step.
|
No
|
Go to the next step.
|
||
3
|
VERIFY RELATED PENDING CODE AND/OR DTC
• Switch the ignition to ON (engine off).
• Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
• Is the other PENDING CODE/DTC also present?
|
Yes
|
Go to the applicable DTC inspection.
(See DTC TABLE [MZ-CD 1.6].)
|
No
|
Go to the next step.
|
||
4
|
INSPECT BOOST AIR TEMPERATURE SENSOR CONNECTOR CONNECTION
• Switch the ignition to off.
• Disconnect the boost air temperature sensor connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Is there any malfunction?
|
Yes
|
Repair or replace the terminal, then go to Step 8.
|
No
|
Go to the next step.
|
||
5
|
INSPECT BOOST AIR TEMPERATURE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND
• Disconnect the boost air temperature sensor connector.
• Inspect for continuity between boost air temperature sensor terminal D (wiring harness-side) and body ground.
• Is there continuity?
|
Yes
|
If the short to ground circuit could be detected:
• Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected:
• Replace the PCM (short to ground in the PCM internal circuit).
Go to Step 8.
|
No
|
Go to the next step.
|
||
6
|
INSPECT BOOST AIR TEMPERATURE SENSOR
• Inspect the boost air temperature sensor.
• Is there any malfunction?
|
Yes
|
Replace the boost air temperature sensor, then go to Step 8.
|
No
|
Go to the next step.
|
||
7
|
INSPECT PCM CONNECTOR CONNECTION
• Switch the ignition to off.
• Disconnect the PCM connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Is there any malfunction?
|
Yes
|
Repair or replace the terminal, then go to the next step.
|
No
|
Go to the next step.
|
||
8
|
VERIFY THAT DTC P0097:00 TROUBLESHOOTING IS COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS.
• Run the vehicle under the FREEZE FRAME DATA stored condition.
• Is the same DTC present?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the PCM.
Go to the next step.
|
No
|
Go to the next step.
|
||
9
|
VERIFY AFTER REPAIR PROCEDURE
• Perform the after repair procedure.
• Are any DTCs present?
|
Yes
|
Go to the applicable DTC inspection.
(See DTC TABLE [MZ-CD 1.6].)
|
No
|
DTC troubleshooting completed.
